Why clear the DNS cache?
Have you been having connection problems with Windows 10 or Windows 11? Anything from websites not loading or opening properly, not being able to play online multiplayer games, or even Windows updates and other services not working.
There is a good chance that running the flush DNS command could resolve these issues, as the DNS cache can cause many issues if it’s storing incorrect data.
If clearing the DNS cache does not help then your router might also have a DNS cache. Or it could be your internet provider that’s storing the cache, and you will need to wait until they clear this. But this can sometimes be a few days depending on your provider. So using a VPN service could help resolve this.
